摘要
采用自制的复合铝絮凝剂CPAC处理微污染原水。实验结果表明,CPAC去浊性能及卫生性能均优于PAC。在同等混凝剂投量的情况下,CPAC出水中残余铝含量小于PAC,且O/A比值越高,出水残余铝含量越低。在B为2.0,混凝剂投量2.7mg/L条件下,PAC处理出水残余铝浓度为0.156mg/L,而O/A比值分别为0.05和0.1的CPAC出水残余铝含量则分别为0.13mg/L和0.125mg/L,均低于生活饮用水卫生标准;此外,在试验考察的pH范围内,CPAC出水中残余铝含量均优于PAC,最佳pH在7.2左右。
Purification study of river water was carried out adopting composite coagulant CPAC. The results show that CPAC was better than PAC in treating light-polluted water. At the same dose of coagulant, residual aluminum of CPAC was little than that of PAC. The more O/A, the little residual aluminum. When B was 2.0 and CPAC dose was 2.7 mg/L, residual aluminum of PAC was 0.156 mg/L and that of CPAC was 0.13 mg/L and 0.125 mg/L respectively when O/A was 0.05 and 0.1 .Furthmore,the best pH is about 7.2 when treating river water by CPAC.
